Apple finally released the long awaited refresh to the Macbook Pro line. The i7 2.66Ghz is available only for the high-end 15″ and 17″ models, according to Apple marketing for this configuration battery power should be around 8-9hrs (wow!). The rest of the 15″ got the i5 series ranging from 2.4 to 2.53Ghz, also it is interesting that the 13″ still feature a slightly bumped Core2Duos from 2.4 to 2.66Ghz and feature a 10hrs batter life.
